esh_logo Accessibility Policy and Code of Conduct

Described herein, the Evidence Synthesis Hackathon (ESH) refers to an event series, consisting of in-person or online activities undertaken by voluntary groups of individuals (Participants). The ESMARConf (Evidence Synthesis and Meta-Analysis in R Conference) is the ESH’s flagship annual online conference. Participation in both ESH and ESMARConf are always free and do not require any form of payment, though attendance at individual events may be limited to a specified number of Participants by the Organisers. Participants at ESH events are expected to contribute in a meaningful way to group activities. The Organisers of ESH are currently (as of 2020) Neal Haddaway and Martin Westgate, and the lead organiser of ESMARConf (as of 2022) is Neal Haddaway.

Aims and objectives of the Policy

The Evidence Synthesis Hackathon (ESH) and the organisers of ESMARConf are committed to equality and ensuring an accessible workflow, and equal and fair treatment of its participants interacting during the conference.

In the UK, The Equalities Act 2010 identifies a list of “protected characteristics”. It is illegal for an organisation to harass or discriminate against anyone because of their age, disability, gender reassignment, marriage or civil partnership, pregnancy or maternity, race, religion or belief, sex, or sexual orientation. The organisers of the ESH oppose all forms of unlawful and unfair discrimination and will not, through coordinating activities or by allowing or endorsing behaviour of its participants in their activities associated with the ESH, discriminate on the grounds of any protected characteristics.

The ESH and ESMARConf seeks to foster an accessible working environment free of discrimination and prejudice. All participants will be treated fairly, with respect, and will be given equal opportunity in every aspect of their work within the group.


The organisers of the ESH and ESMARConf seek to ensure the group’s activities are accessible as possible to its participants. To that effect, the organisers will ensure the following:

Code of Conduct

Raising a concern/complaint

Any participant or organiser of the ESH or ESMARConf who feels they have been treated unfairly on the grounds of a protected characteristic are encouraged to raise their concerns with an organiser (anonymously, if desired).

Complaints can be submitted by email to the conference organiser (, to the organiser’s line manager at the Stockholm Environment Institute (, to a member of the conference organising team (see, or using this anonymous form:

The organisers will investigate the complaint, listening to all participants involved. (If the complaint is against an organiser, that member will not be involved in the investigation).

If the complaint is against a particular individual, this person will have the opportunity to express their point of view. The person making the complaint will also have this opportunity. If the complaint is against the ESH or ESMARConf as a whole, the organisers must work to ensure that such discrimination is not repeated in the future, and must inform the participants of how they propose to do this.

Any decision to exclude a person from the ESH or ESMARConf due to discriminatory or harassing behaviour will be made with reference to this Policy. The ESH and ESMARConf organisers will support people who feel they have been harassed or discriminated against, and will not victimise or treat them differently as a result.
